SI-3010LLSL: 1.5 A, Ultra-Low-Dropout, 1.1~3.3 V Regulator

Designed to meet the high-current requirements in industrial and consumer applications; embedded core, memory, or logic supplies; TVs, VCRs, and office equipment, the SI-3010LLSL voltage regulator offers the reduced dropout voltage and low quiescent current essential for improved efficiency. This device delivers a regulated output at up to 1.5 A. Integrated thermal and overcurrent protection enhance overall system reliability.

An npn pass element provides a dropout voltage of less than 300 mV at 1 A of load current. Regulator accuracy and excellent temperature characteristics are provided by a bandgap reference. Low output voltages eliminate the need for expensive PWM buck converters. The low dropout voltage permits more efficient regulation before output regulation is lost. Quiescent current does not increase significantly as the dropout voltage is approached, an ideal feature in standby/resume power systems where data integrity is crucial. An LS-TTL/CMOS-compatible input gives the designer complete control over power up, standby, or power down.

This devices is supplied in a fully molded 8-lead miniature surface mount package (tape and reel) with enhanced power-dissipating qualities.
